A CORPORATION OF NEW JERSEY MACHINE FOR USE IN FORMING HEEL SEATS 0NBOOT AND SHOE SOLES Application filed April 11, 1927, Serial No.182,676, and in Great Britain April 14, 1926. i

This invention has reference to machines for use in forming heel seatson boot and shoe soles for the reception of wood or like heels having aconcave upper surface and more especially to the type of machine inwhich the heel end portion of the sole is deformed by a plunger and aform plate and a skiving knife is provided whereby the heel seat is inpart severed from the sole, leaving,

f usually, an approximately U-shaped marginpedited; means whereby, whendesired, a

shoulder extending across the surface widthwise of the sole may beproduced to form an abutment for the breast edge of the heel which,additional to or instead of the shoulders or the tabs on the sides ofthe sole, may

be utilized to determine the position of the heel on the shoe, and inwhich machine the marginal portion of the sole may be held yieldinglywhilst the central. portion or main part is being deformed for thepurpose stated.

Further, when using machines of the type referred to as heretoforeconstructed for forming a heel seat 011 a shoe sole that is alreadystitched at the forepart and at the waist to the shoe, a practicaldifficulty arises due to the following:

It is not readily possible in everyday fac tory practice to start andfinish the sole-sewing at the precise distance from the heel end of theshoe and so that the first and last stitches are located preciselyopposite to each other on the shoe, as to leave unconnected to the shoethe exact desirable length of the heel end of the sole for presentationto the heel seat forming instrumentalities. It is therefore customary tobegin the stitching at one side and to finish it on the other side ofthe shoe sole nearer to the heel end than is no required and for theoperator who is subsequently to form the heel seat on the sole to severby a hand knife one or more stitches on each side of the sole accordingto the re quirements for the purpose stated of the particular shoe aboutto be operated on. This not only requires considerable skill andjudgment on the part of the operator and the frequent offering of theshoes to the seat forming instrumentalities to ascertain whether enoughstitches have been severed, but there is the risk of his cutting toomany stitches on either one or both sides and also the risk of hiscutting into the leather owing to the fact that the sole is drawn by thestitches into very close contact with the marginal portion of the upperon the insole. Although attempts have been made to provide means wherebythe operator mayinsure the accurate severing of the stitches for thepurpose stated before the shoe is presented to the heel seat formingmachine, the means have been too complicated for adoption in everydayfactory practice.

A further feature therefore of our invention is the provision of meansof extremely simple character whereby the severing of the stitches asaforesaid may be effected with absolute accuracy whilst the operatorpresents the work to the heelseat forming in strumentalities.

The above and other features of our invention will become apparent fromthe following description of a preferred constructional form of machineincorporating the several features of our invention.

The said preferred constructionalform of our machine is illustrated inthe accompanying drawings in which Fig. 1 is a side elevation of theillustrated machine, certain severing cutters being omitted so as toexpose to view a shoe in position; Fig. 2 is also a side elevationshowing more in particular the severing cutters; Fig. 3 is a frontelevation of the complete machine; Fig. 4 is a plan view thereof; Fig. 5is a view on an enlarged scale of an important feature of our invention;and Figs. 6 and 7 are plan and side elevations respectively ofstationary cutters for severing sole attaching stitches. y

In said drawings the numeral 6 indicates the head or frame of theillustrated machine to support the working parts, which head is carriedby a standard 5. At a position convenient to the operator the headcarries a horizontal form plate 8 having a U-shaped opening the uppermarginal portions 9 of which are inclined to the horizontal and form aconcave portion of the plate.

Arranged for movementin a vertical hearing 12 we provide a plunger 60whichiscarried on a stem 61 and by movement of which plunger in thevertical direction downwardly the central part of the heel end of a soleplaced on the form plate 8 will be bulged throughtheopening therein, andthe bulgedthrough portion may be in part severed from the sole by a:skiving knife 26 arranged for movement below the plate 8 in suitableguideways. 1' Y Surrounding the vertical spindle 61 we provide asleeve64 the lowerend 'of which sleeve carries presser feet 66, 68,having inclined lower faces 70, 72, respectively, the inclination ofsaid plates being similar to that of the marginal inclined faces 9 ofthe form plate 8. Interposed between the sleeve 64 and a collar 62 onthe spindle 61 is a spring 7 6 that tends to press the presser feet 66,68, downwards towards the inclined faces 9 of the form plate, thedownward movement of said presser feet being limited by a shoulder 69 onthe sleeve 64 engaging against the forwardly projecting part of theplunger 60. While the term plunger has been appliedto the portion of themachine identified by reference numeral 60, itwill'beclear that thepresser feet 66, 68, together with the plunger 60, serve to distort thesole and may be considered jointly as a plunger.

Arranged for movement in the plane of the 'skiving knife .26 in thedirection transversely of the machine we provide cutters such forexample as 50 which are arranged for movement from the opposite sides ofthe machine towards the centre and are intended for J: severing themarginal portion from the shoe sole;

The foregoing ate as follows I When the heel end of a shoe sole has beenarts are arran ed to 0 erv i b placed on the form plate 8 the operatorby depressing a treadle will depress the plunger 60 and with the plungerwill move the presser feet 66, 68. The plunger and pressers will moveuntil the pressers firmly hold the marginal portions of-the sole againstthe inclined In this position the pressers 66, 68, will very firmly holdthe marginal portion of the sole against the inclined faces so that theycannot become displaced when thesevering cutters 50 are actuated.

m- Foroperating the plunger 60 and pressers 66, 68, we provide a treadlelever (not shown) that we connect by a rod let to one end of a rockinglever 15 carried on the pivot pin 16 in the upper part of the frame orhead. The forward end of said rocking lever is con nected by a link 18to the rear end of a second rocking lever 19 which is supported forrocking movement on a pivot pin 20, the forward endof which rockinglever19 has a rounded head 21that engages against the upper end of thespindle 61 and by which the plunger and presser feet'may be actuated .asalready described. The plunger 60 is normally held raised'some distanceabove-the form plate 8 by a spring 13 and may be lowered by depressionof the rod 14.

We provide an adjustable stop pin 22 on the rocking lever 15'to engageagainst a block 23'on the head of'the machine, by'which stop the extentof downward movement of the plunger may be limited as may be desirableaccording to the thickness of the shoe sole to be operated on.

For the purposeof operating the severing cutters 50 we provide thefollowing 1neans:-

Secured to the front of the head 6' we provide two brackets 30, 31, oneon each side of the form plate 8 and of the plunger. Each bracket isprovided with an arcuate slot 32 through which projects a bolt 33 thatcarries a bearing 34'for a sleeve-like member '35. The bearing 34 isadapted to be.

clamped by a clamping screw 37 so-as'fir mly to grip the member 35.Passing through the member is a spindle 39 which at its outer end ispivotally secured to a lever 42 which is at its rear end'connected by alink 43 to the machine head and at its front end is provided with ahandle-l5. Secured to the spindle 39 by its shank48 is a severing cutter50 the lower extremityof the cutting edge of which is in the plane(substantially) of the upper face of the skiving knife and the shank 48engages in a slot in the sleeve member 35 so that the spindle 39 andsevering cutter 50 are adapted to be moved in the direction axially ofthe spindle; By adjusting the position of the sleeve like member 35about its axis the angular position of the severing. cutter may be setso that when the handle lever 42 is actuated the severing cutter 50 willsever the leg on one si'deof the U-shaped trimming '(of course thecorresponding cutter 50 on the other side will be instrumental insevering the other'leg). If there is adhering a thin layer or flap itwill be merely necessary to move the severing cutters 5 0 until theyreach the longitudinal median line of the sole when the said flap andthe legs of the U-shaped marginal portion will both or all have beensevered so to be completely detached from the sole. If there is no flapas aforesaid left attached to the sole, on the completion of thesevering cuts by the cutters 50 the sole will merely have a shoulder ateach side. If however a thin flap was left adhering to the upper face ofthe sole then, when the cutters 50 have been operated, they will notonly form shoulders on each side but a shallow one across the face ofthe sole also. lVhether the shoulders will be undercut or not dependsupon the adjustment of the parts as already described. It has beenpointed out that some heels have a concave breast face (viewed in plan)and therefore it is desirable to cut the shoulders not at right anglesto the longitudinal median line of the sole (which would be suitableforheels having a fiat breast face) but at some less angle according to theshape of the heels to be attached to the shoes and for this purpose theoperator will slacken back the screw and adjust the bearing along thearcuate slot and again clamp the parts in adjusted position.

In order to insure accurate positioning of the shoe there are providedtwo gauges 53, 5-1, against which the heel end of the shoe is engaged.The former of these engages the heel end so as to determine the positionthereof laterally and the other, 54, to determine the positionlongitudinally of the shoe. The gauge 53 is yieldingly supported so thatthe workman when he has engaged the heel end of the shoe therein canpush this back until the shoe engages against the gauge 54. There ispreferably also a gauge 56 against which the operator holds the forepartof the shoe and this gauge is carried on a pivot 57 on lugs 58 so thatthe operator may lift the gauge and swing it out of the way if and whenhe does not require to use it. All the gauges are adjustable.

Secured to the form plate and having their longitudinal median line insubstantial align ment with the outer edge of the tapering marginalportion of the form plate, we socure stitch severing cutters 80, theupper surfaces of which may be flush with the underside of the formplate and the lower frontparts of which are chamfered off. The cuttersmay be adjustable either in the plane of or in the plane perpendicularto the under face of the form plate and their cutting edges may be inalignment or at an angle to each other. They may also be adapted foradjustment forwardly and backwardljy of the plate so that they may beadjusted to suit different sizes of shoes. They will be made wide enoughso that they will serve the purpose described for several sizes of shoeswithout requiring adjustment. Although the severing cutters areillustrated as being clamped to the form plate in order to effect theabove-mentioned adjustment, it is clear that these cutters may ifdesired be formed integral with the form plate and hay constitute partsthereof.
